Re: Response to Exception Request for Street Improvement Conditions- TPM20-0010; APN 078-270-040 Dear Tristan, Department of Public Works (PW) reviewed the applicant exception request to waive street improvements for
the subject project. The project is proposing to divide one parcel into four parcels. This project is located in Oroville Urban area.
Installation of curb, gutter and sidewalks: There are no existing urban improvements (curb, gutter, and sidewalk) in the vicinity of the project site. Additionally, urban improvements do not seem to be consistent with the existing adjacent infrastructure and with the character of the surrounding land use. Therefore, PW supports the applicant request to waive the construction of curb, gutter, and sidewalk for both the frontage street and the interior street. Instead, the applicant would be required to install a S-18A road approach. Please see the revised COAs #7 and #8 on the next page. Street construction: PW has consistently conditioned TPM and TSM for street improvements per County Improvement Standards. COAs #7 and 8 are standard conditions for such projects. Improvement standard RS-2 applies to all land
divisions within County Urban Areas including private street land divisions. The applicable standards for this project is RS-2B for frontage street (Oroville Bangor HWY) and RS-2C for the interior street. Both RS-2B and RS-2C require a cross section of 3” asphalt concrete and 12” aggregate base. City of Oroville has a similar
improvement standard as well except that the City standard specifies 10” aggregate base. PW does not support the applicant request to waive this requirement.
Street name and name signs: Street names and street name signs are required for all streets including private roads per County Code chapter 32. PW does not support the applicant request to remove COA #4. Therefore, COA #4 still applies.
